In an isosceles triangle, the length of each leg exceeds twice the base by 2cm. perimeter is 24. how long is each leg?

Each leg 10 units in length.

Step-by-step explanation:

Since this is an isosceles triangle, both sides are equal which means we can set up a system of equations for this, l will symbolize the legs and b will symbolize the base.

2l+b=24  This equation means that the length of 2 legs and the base will add up to 24.

l=2b+2 This equation means that the length of one leg added to 2 is equal to twice the base.

Now, solve the system, I will use substitution.

Next, substitute the 2nd equation into the first to solve for b.

2(2b+2)+b=24, Solve for b:

4b+4+b=24

5b= 20

b=4, This means that the length of the base is 4, now solve for the length of each leg using either of the equations by plugging in the value of b.

l=2(4)+2

l=10, The length of each leg is 10

i got 86 for this

hope this !

if you need an explanation just ask

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
